SYNOPSIS
</h2>
<p>
<b>#include &#60;pcre2.h&#62;</b>
</p>
<p>
<b>int pcre2_set_max_varlookbehind(pcre2_compile_context *<i>ccontext</i>,</b>
<b>  uint32_t <i>value</i>);</b>
</p>
<h2>
DESCRIPTION
</h2>
<p>
This sets a maximum length for the number of characters matched by a
variable-length lookbehind assertion. The default is set when PCRE2 is built,
with the ultimate default being 255, the same as Perl. Lookbehind assertions
without a bounding length are not supported. The result is always zero.
